My 100 pound yellow lab will do anything to stay near me. I had to add a combination of lattice topper with three vertical feet of metal rabbit fence and a fourth foot as inward overhang to end his jumping over our formerly six foot wooden fence and waiting for me at the front door. One time prior, my neighbor called me at work when my dog decided to play cat and pace back and forth along the three inches of fence topper. It was similar to this scenario:

Fun^^^ Mine will only consider nearing stuff as technical as the wall at the end of the Front Range clip to follow me. Now that they are middle aged, they usually just look at stuff like that, whine, and let out anxious barks. They fear their own climbing limits more than that little dog. I tend to be considerate of what they are comfortable with, but I'll pull them through a short move if that is all that stands in the way of summitting. Paws have to be kept tough to easily hike out after taking on terrain like that.

Dogs getting sore paws doesn't have to become a big deal, but the way it was responded to by the owner snowballed into a big mess in the recent famous case.

Weirdest thing-- After sharing one of my many Houdini-dog stories here yesterday, my dog escaped our fortress for the first time in several years while we were away for the evening. It sure seems like he knew I was telling stories about him finally being contained. He always knows where the weak spot in a containment system is, even when most would be deterred by it. Luckily he just wants to be with us, so he was home 30 seconds after we were. I now must strengthen the confines of the backyard again, or never leave him alone with access to it.

Not climbing/hiking specific, but folks could pick up a few things from this man and his dog:

Somebody dumped this little cat in my neighborhood. The first thing I did when we decided to adopt her was to clip her claws. They were like needles. I regret that I didn't get a picture of her climbing up the brick.
